Is there someone who build Suzy Jackson preamp ? I'am block with the code. Everything is compile and program to the micro but all the fonction like power on, source select , does'nt work. Someone can help me as i really want to make that project successfull. Another question: Shall we connect some special pin on the vfd to reset? Actually i need to turn power off to change the display..

Hi Dayal,
For the power supply it is not that hard. You can refer to Mark Henessy Preamp on google which is a really great project. Basically what you need is -15va-0v-15va power supply. Also, for the digital aide of the project you need 0-5Vd power supply. Good luck!
